Weinstein Année de publication : 2007 Article en page(s) : 35 - 42 Langues : Anglais (eng) Catégories : Autres descripteurs réutilisation de l'eau potable ; micropolluants ; RECYCLAGE DE L'EAU ; risques Thésaurus Agrovoc Santé publique Résumé : This paper presents a three-tiered approach for the preliminary assessment of micropollutants in recycled water. A risk quotient is calculated by comparing measured concentrations against benchmark values. Tier 1 corrresponds to regulated chemicals; the maximum contaminant level in drinking water is used as benchmark value. Tier 2 corresponds to unregulated chemical with toxicity information; slope factors or risk specific doses are used to calculate benchmark values. Tier 3 corresponds to unregulated chemicals without toxicity information. The "Threshold of Toxicological Concern" concept is used to calculate benchmark values. The characterization of chemicals of concern following reverse osmosis in a water reclamation plant and the application of the three-tiered approach for the evaluation of the potential health risks is presented.
